    BEST MODE FOR CARRYING OUT OF THE INVENTION

    [0027] 32. Referring now to the drawing figures, and in particular to FIG. 1, a first preferred embodiment according to the present invention will be described in detail. FIG. 1 shows an elevator car 100 positioned within a hoist-way shaft (not showing). A pair of magnetic vertical bars sections 142a-142b, is allowing to have a magnetically capability in order to holds the weight of the stationary ropes, on it’s exposes magnets tile sections, and showing to be able to hold in place the exposed seeing pair of stationary ropes 120-124,and 126-128,. Each pair of ropes are tensioned on the top end of the vertically hoist-way shaft 130-132, and on the bottom end of the vertical hoist-way shaft, 138-140. preferably using conventional certified rope tensioning systems devices. On top (roof) of the elevator car 100, (64) very schematically is showing the arrangement of the main parts of the vertically gears traction system. (Please note, that for the better view, the traction system representation is very schematic in FIG. 1 ,intended to show only the traction motors (movers), and the dual shafts busbars assembly, connected directly with the pair of the traction sheave drums assembly) Referring now to particular FIGS. 2 and 3 enumerate the all parts, and describing the functionality of the preferred embodiment of this invention. An electrical motor 138, is driving the main shaft 148a, part of the dual shaft busbar traction assembly, further is driving the 1 to 1 ratio gearbox contra-rotation assembly, and is defined as the 1 to 1 ratio speed traction gearbox unit 152. ( please note, that the gears system showing in FIG. 2.a, like the 1 to 1 ratio gearbox traction unit, in order to operate, needs only two gears transmission wheels system). In FIG. 2 the embodiment is using the 1 to 1 ratio, gearbox unit transmission system, is employing four gear transmission system assembly, with the same mechanical functionality purpose described in FIG. 2.a), and in this way is connected to the second driving shaft 148b.(part of the same mechanical system defined as the 1 to 1 ratio, dual driving busbar shaft transmission assembly).The gearbox 152 ( two, or four gears 1to1 transmission configuration) is designed to turn the dual driving busbar-shafts assembly in a opposite direction. At the opposite ends of the driving shafts 148a, and 148b, is installed the ropes climbing driving sheaves traction drums assembly 156a and 156b. The connections between each front end shaft, part of the dual busbar-shaft assembly, and the rope climbing sheaves drums system is made by the 1 to 7 rotational speed multiplication, by using a planetary gearbox transmission units,136a, and 136b. In this configuration, the traction motor 138 is rotated 7 times faster than sheaves traction drums, and is creating the necessary power thrust to move the elevator car up. On the busbar- shaft 148.b. is installed a Flying wheel-Governor-Generator assembly, 46. (158, for FIG. 2.), The flying wheel-generator-governor assembly is designed not just to monitor the speed of the car 100, but, it is employed to physically control the speed of the elevator car in any wanted, or unwanted situation. The governor flywheel-generator assembly, 46 is designed to be rotated one way crank, one the bearing, K.3., and is activated only when the elevator car is moving down. Further on the driving shafts 148.b ( part of the dual shafts busbar assembly) is installed a triple disc brake system 154.a,154.b. 154.c. The brake discs assembly is designed to hold one or multiple brake calipers systems ( not showing ). The brake discs 154.a, 154.b.,154.c. are designed to rotate only one way crank on the bearing, K.1. In this configuration when the elevator car is moved up, the utility disc brakes are stationary. The entire traction driving assembly is held in place on top of the elevator car platform by multiple brackets, 142.a to 142.j. Further the elevator car 100 is guided on the elevator hoist-way 144 by a pair of conventionally guided rails rises 150.a, and 150.b. FIG. 3 shows a side elevation of car 100 showing the visible side of the exposed traction components, like the vertically stationary ropes 124-120, down tensioned by the tensioning devices 138, 140. On top (roof) of the elevator car 100 (64) is visible a driving motor (mover) 134, a traction sheave drum 136.a., portion of the 1 to 1 ratio gearbox transmission 152, ( please note that the traction system visible in FIG. 3. is referring to the embodiment in which the transmission of the 1 to 1 gearbox traction is using four gears wheels transmission system to turn in opposite direction the two driving shaft, part of the dual driving busbar shaft assembly ), a brackets assembly 138- 142, and a designated empty space, 160, is envisioned for having a dual practical interest, like to create a phonic isolation, and a storage space device, designed to house the energy storage device, like a battery pack, supercapacitors etc.

    [0028] 33. FIG. 4, FIG. 5, and FIG. 6 described in detail the most important part of this invention, defined as the magnetic vertical bars frames assembly sections. FIG. 4 Shows an elevator (shaft) hoist-way wall 30, and the brackets 28,and 30 bolted into the elevator hoist-way wall. A sheet frame system, metallic or nonmetallic design to be the magnet’s hoist holder 26, is secured in place by the brackets 28, and 30. Further on the magnets vertical bars frame 26 is installed the corresponding magnets tiles (plates) 24 bolted, or glued on the frame 26.The magnets tiles 24 could be installed on the magnetic vertical bars frame without any vertical gapes ( vertical space),( not shown ) on the frame 26, or with a designated vertical gapes, depending of any particular elevator project. FIG. 5 Showed that in this embodiment the magnets tile 24 are installed with a designated vertical gap (vertical spaces) on frame 26. Further on the magnetic vertical frame bars assembly, designed to hold the magnets tile in place, on the face of the said magnets tile, is magnetically held in place the stationary traction ropes 22.a, and 22.b. FIG. 6 Shows the side view of the magnetic vertical bars assembly 20. The stationary traction ropes 22.a, and 22.b ( 22.b not shown ) are engaged by the traction sheave drum 32,( sheave drum not showing, just the stationary rope engagement), and the arrows indicate the direction of engagement. FIG. 7.a. Shows a detailed preferred design of the flying wheel governor-generator assembly, and the associated 1 to 18 ratio gearbox wheels speed multiplication. The governor driving shaft 40 receives the rotation power from the 1 to 1 ratio gearbox wheel 152,( note, for FIG. 7. The 1 to 1 ratio gearbox wheel is notated number 30, part of the 4 wheel transmission gearbox 58, ( not shown ).

    [0029] Further on the driving shaft 40 is installed a 1 to 18 ( note: the transmission ratio could be adjusted in order to fit any elevator project) speed multiplication ratio gearbox system,(is the driving component of the flying wheel governor-generator assembly unit) constructed by a gearbox assembly consisted by the gear wheel 34, gear 36, and gear 38. The gear 36 is installed on the stationary shaft 52. The driving gear wheel 34 is receiving the rotational thrust from the described dual shaft busbar traction main driving system, and is designed to rotate the speed multiplication gearbox unit ( gear 34, 36, and 38) with the flying wheel governor-generator assembly, rotating on the one way crank on bearing K.2. Gear wheel 34 is receiving it’s thrust rotational power from the gear wheel 36, spinning on the stationary shaft 52. The gear wheel 38 is designed to be the main driving of the 1to18 rotary speed multiplication gearbox system driving the flying wheel governor-generator assembly. and receiving it’s rotational thrust power from the main dual traction busbar assembly driving system. The driving shaft 40, being part of the flying wheel governor-generator assembly unit, is envisioned to be the main shaft rotor of the flying wheel-governor-generator unit. In this configuration the rotor of the generator assembly might be connected with the driving shaft 40, by a coupling device, connecting the said shaft of the generator with it’s rotor driving shaft 40. In some particular design configuration, the driving shaft of the generator is a continuation of the driving shaft 40. To dissipate the rotational kinetic energy, the flying wheel 46, the generator rotor 40, and the analog governor rotor ( part of the high speed 1to18 ratio driving shaft 40) is rotated one way crank on bearing K.3. and K.4. The purpose of this gears design configuration is to prevent the utility brakes system from wearing out when the elevator car is descending, and has the command to stop at any particular floor. In operation after the elevator car stops at any floor, the shaft 40 has to comes to an abrupt stop, but because of the one way crank bearings K.3 and K.4, functioning, the flying wheel 46, the generator rotor 40, and the rotor of the governor-flying wheel generator is still rotating 10, 15 seconds, ( like the bicycle traction wheel gear) dissipating the gravitational rotational kinetic energy, generating electricity, and protecting the utility breaks. This described mechanical component is rotated at a high speed (1to18 ratio) in the same direction with the driving shaft 40. The governor corona stator 46 is installed on the mainframe on top of the elevator car 64.(In FIG. 1 noted elevator 100). Further a system of brackets 142.a to 142.J are designed to secure all the described mechanical devices in place on top of the elevator car 64. ( In FIG. 7 and FIG. 8 the brackets notification is 46.a, 46.b, 56, 58, 62.) The entire gearbox speed rotatory multiplication system, including the flying wheel governor-generator assembly, is designed to be in a stationary position when the elevator car 100 is moved up, or seating in a parking position. The governor system, the flying wheel 46, and generator 66 is activated gravitationally at a descending down command of the elevator car 100 (64), creating electricity. In the second embodiment, FIG. 8 represents a continuation of driving shaft 32 from FIG. 7. On the driving shaft 44 is installed several mechanical assemblies, and is showing a dual one way crank bearings rotating utility disc brake assembly 52.a, and 52.b. In operation the brake discs assembly is stationary, when the elevator car 100 (64) is moving up. The utility brakes become activated when the elevator 100 (64) is moving down, most preferable gravitationally. For further other applications, a gear wheel 48is installed on the driving shaft 44. At the front end of the driving shaft 44 is installed the traction sheave drums assembly 40. In FIG. 7.a, and FIG. 8, the rotational speed of the traction sheave drum 156.a, (156.b not showing) is reduced by 1 to 7 ratio, between the driving motor 138 ( not showing ) and the dual busbar driving shafts assembly 148.a, and 148.b for FIG. 2.a.( for FIG. 8, is a shaft 44.) In FIG. 7, and FIG. 8, the driving shaft 32, is a continuation of the driving shaft 44. Inside the traction sheaves,156.a, and 156.b is a schematic representation of the planetary gearbox system 136.a and 136.b, for FIG. 8 is 56, and a traction drum traction 40.for FIG. 8. In this configuration the reduced speed of the sheave traction drums 156.a and 156.b ( 40 for FIG. 8 ) is translating into high torque (1 to 7 ratio) traction of the said sheave traction drums system, and creating the necessary ascending power needed in order to engage the stationary ropes 42. FIG. 8 ( for FIG. 7.a not showing ). Further the entire mechanical assembly from FIG. 8 is held together by the brackets assembly 46a, 46b, and 46c. All the moving parts drawing in FIGS. 7, and 8, Is served by the appropriate bearing system assembly, like bearings 54a, 54b, 54c, and 54d showing in FIG. 8, and the bearing assembly 58a, 58b, and 58c. showing in FIG. 8. For FIG. 7.a visible are the bearings 54.a,54.b,54.c,54.d,54.e,54.f,and 54.g. All the mechanical components in FIG. 7.a are held together by the brackets assembly 142.a,142.b,142.c, 142.d,142.e142.f,and 66b. FIG. 9 is a magnified representation of the second embodiment described in FIG. 3 The drawing from FIG. 9 shows the rotational direction of the visible mechanical elements, like the traction motor (mover) 54 rotating in the opposite direction with the traction sheave 56, facilitated by the gearbox system 50a, 50b, 50c, and 50d. This mechanical configuration is not limited only for a 1 to 1 rotational transmission ratio, achieved by 4 gearbox wheels assembly system. Some elevators projects might recommended to use only 2 Wheels gearbox transmission assembly (describing in FIG. 2.a, and FIG. 7.a,) to secure the same contra rotational traction of the dual shaft busbar traction system. The arrows direction of the driving traction system showing that the elevator car 100 (64) is moving up, climbing the rope system 62a, and 62b. The mechanical driving system visible in FIG. 9 is held in place by the visible brackets system 54a, 546,and 54c. Visible under the mechanical traction system, is an empty space 58 design to house the power storage devices, and to create a phonic isolation space able to protect the passengers from any noise induced by the traction system in operation

    [0030] 34. FIG. 10 shows a schematic plan view configuration of the traction system pointing to the rotational parts movement when the elevator car 100 (64) is in the moving up operation. In this configuration the driving motor by rotating in the clockwise direction, the primary shaft 148.a will transmit the rotational power to the1 to 1 ratio gearbox assembly 152, and to the planetary gears system 136.b, further turning the traction sheave drums156.b, and 156.a. The breaks discs 154.a, and 154.b are alloyed to stay stationary by the function of the one way crank bearing k.1 ( not showing ). So the driving shafts 148.a, and 148.b is rotated freely, engaging only the sheave traction drums assembly 156.a, and 156.b. Further the main gearbox 152 will rotate the driving shaft 156.a into the opposite direction. The shaft 156.b will turn the planetary gearbox system 136.b of the sheave traction drum 156.b, in the same direction as driving shaft 148.b. Further the driving shaft 148.b will be not turn the one-way crank brakes disc 154.a, 154.b, and the 1 to 18 ratio speed multiplication of the flying wheel-governor-generator gears assembly allowing to stay stationary by the function of the one way crank bearing system K.2, and K.3 ( not showing ). This simple mechanical traction system has low numbers of moving parts, when the elevator car 100 (64) is moving up. In this configuration only the driving motor (mover) 138, the transmission 1to1 gearbox 152, and the sheaves traction drums 156.a, and 156.b, will be rotated engaging the stationary ropes 64.a, and 64.b. The driving motor is powered by the power catenary- pantograph panel assembly 94. The traction system further is served by the necessary bearings system, and the brakes assembly ( not showing), and the entire system is mounted on the platform (mechanical motherboard) 64 on top (roof) of the elevator car.

    [0031] 35. FIG. 11 shows a schematic plan view rotational configuration of the traction system when the elevator car is moving down. In this configuration the elevator car 100 (64) is designed to descend gravitationally. As the car 100 starts to move down, the driving motor 138 is turning in reverse by gravity, producing electricity. Before the elevator car 100 starts to descend the discs breaks system 154.a, and 154.b, slowly (or a snap, abrupt desingagement) will release the pressure of the shoes breaks inside the brake calipers ( not shown ), allowing the car 100 to move down. In the process, the main gear box 152 will turn the driving shaft 148.a into the opposite direction, allowing the one way bearing crank flying wheel-governor-generator gears assembly to become rotating, by gravity, and to activate the high speed ratio multiplication 1to18 speed ratio of the flying wheel gearbox, 34, 36, and 38 assembly. Further the flying wheel 46, and it’s shaft 40 will turn the generator’s rotating shaft with the same speed as the flying wheel 46. (the system is showing in FIG. 2.a). The high speed rotation of the flying wheel-generator-governor assembly 46 will create a desired descending resistance preventing the car from accelerating out of control, and protecting the utility braking system. This movement has a dual practical interest, like the more multiplied the speed in reverse the traction motor, and flying wheel-generator-governor assembly has, the more electricity is produced, and less energy, is needed for the braking system to stop the elevator car. However, descending from the nominal speed, before the car 100 arrives to a full stop at any designated floor, the utility breaks system will act alone to stop the car 100 for bringing it parking position. So for some elevator projects additional breaks system might be needed, or for some projects, a super high speed, and high friction with low heat operation generator device might be employed, to keep functioning until the elevator car arrives at a complete stop. Before bringing the car to a complete stop, the speed control governor-generator assembly will not be able slowing the car 100 to a complete stop, due the low speed of it. As soon as the utility breaks is activated the governor will analog get deactivating itself, due to the low speed of the descending car 100. In conclusion, even though the utility brakes are in use only 3, or 4 seconds at every command stop of the car 100, there could be a lot of wearing of the utility brake shoes, as a result of the weight, and velocity of the car 100 managing not to use any contra weight in operation. So, with today’s advanced technology in a breaking system device ( there are ceramic, and other composite high friction materials with low heat operation might be adapted for any future rope climbing elevator projects.) ,this invention will cover the today high demand for new elevator traction systems adopted to operate at very low energy consuming technology, and able to serve the vertical transportation industry. While the preferred embodiments have been described herein, it is acknowledged that the generally or specific features may vary in part or totally, without departing from the scope of the presently claimed invention.
